Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate
What is Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate?
Polyglyceryl-4 Diisostearate/Polyhydroxystearate/Sebacate is a multifunctional blend of non-ionic surfactants derived from natural fatty acids and glycerol, primarily sourced from vegetable oils like castor and rapeseed. Polyglyceryl-4 diisostearate features a polyglycerol backbone esterified with isostearic acid, polyhydroxystearate involves hydroxylated stearic chains from castor oil derivatives, and the sebacate component stems from sebacic acid, a dicarboxylic acid from plant lipids. In cosmetics, it belongs to the cleansing and emulsifying agent category, commonly found in micellar waters, makeup removers, and light lotions. It works by reducing surface tension between oil and water phases, forming stable micelles that encapsulate lipophilic impurities for rinse-off without stripping skin. This enables effective yet gentle removal of makeup and sebum while maintaining emulsion integrity.
